Contract VerificationCopy Anchor Link

// Verify contract source code matches deployed bytecode
async function verifyContract(address, sourceCode, compilerVersion) {
  // Get deployed contract info
  const response = await fetch(`${API_URL}/wallet/getcontractinfo`, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ value: address, visible: true })
  });
  
  const contract = await response.json();
  const deployedBytecode = contract.bytecode;
  
  // Compile source code (pseudo-code)
  const compiledBytecode = await compileContract(sourceCode, compilerVersion);
  
  // Compare bytecodes (excluding metadata)
  const verified = compareBytecode(deployedBytecode, compiledBytecode);
  
  return {
    verified,
    contractName: contract.contract_name,
    abi: contract.abi,
    creator: contract.origin_address
  };
}

Best PracticesCopy Anchor Link

1. Cache Contract InfoCopy Anchor Link

• ABI doesn't change after deployment
• Cache to reduce API calls
• Update cache only when needed

2. Validate ContractsCopy Anchor Link

• Check bytecode exists
• Verify ABI structure
• Confirm expected functions present

3. Energy MonitoringCopy Anchor Link

• Track consumed_energy growth
• Monitor for unusual consumption
• Alert on high energy usage

Common ErrorsCopy Anchor Link

Use CasesCopy Anchor Link

• Contract Verification: Verify deployed contract matches source
• ABI Extraction: Get contract interface for interaction
• DApp Integration: Load contract details dynamically
• Analytics: Track contract usage and energy consumption
• Security Auditing: Analyze contract bytecode and functions
